BED-BOTTOM.

SPECIFICATION forming part of .Letters Patent No. 272,076, datedFebruary 13, 1883.

Application filed December 14, 1882. (No model.)

To all whom it may concern:

Be it known that I, HENRY A. MUELLE R,a citizen of the United States,residing at New Haven, in the State of Connecticut, have inventedcertain new and useful Improvements in BedBottoms, of which thefollowing is a specification, reference being bad therein to theaccompanying drawings, wherein- Figure 1 is a plan of my invention. Fig.2 is a plan of the lower frame of the bedbottom. Figs. 3,4, 5, 6,7, 8,9, 10,11, 12 are detail views. Fig. 13 is abroken plan ofa modification.Fig. 14 is an elevation of same. Fig. 15 is a side view of thebed-bottom, and Figs. 16 and 17 are detail views.

My invention has for its object to provide a bed-bottom which is capableof adjustment both longitudinally and transversely, so that it can bemade to fit any size of bedstead.

My invention accordingly consists of the novel combination, arrangement,and construcparticularly tion of parts, as hereinafter more Referring tothe accompanying drawings,A represents abed-bottom composed of upper andlower frames, B B, respectively, springs (J G, and slats or bars D D.The frame B is composed of side and end rods, 1) .b, respectively,having reversely-threaded ends I), which are connected together bysleeves or unions E, having right and left threads, 0, corresponding tothose on the ends b so that when said sleeves are turned the frame B isexpanded or contracted longitudinally or laterally, as desired. Theframe B is composed of corners f f, having eyes or openingsf, as shownin Fig. 2, and side and end slats or bars, F F, respectively. Said slatsF are composed of a series of sections, f f which slide upon eachotherand are held in line by means of sleeves f which may be formedintegral therewith, as illustrated; or they may be loose or slidingsleeves.

- One or more 'ofthe sections are formed with slotsf while the othershave threaded or tapped openingsf into which pass screwsf f as moreplainly shown in Fig. 12, so that when said side slats are adjusted tothe desired length they are maintained in such position by tighteningthe screws 1". The ends as above described for the sides F. One of theysections, f, has a series of unthreaded or plain openings, f ,and theother a series of threaded apertures, f, as more fully set forth 5 5 inFig. 11, so that when adjusted in length they are rigidly held togetherby screws f. The sides and ends F F are connected to the corner-pieces fby screws f; or. any other suitable fastening may be employed. The sidesF are also connected together by means of bars-G Gr, composed of strips9 g, having loops gg, through which the sides F pass, and are providedwith openings and fasteningscrews 9 as and for the purpose described, 6for the openings and screws in the ends F.

H H represent longitudinal bars, resting on the cross-strips G G, andare composed of sections hh, having slots h. Around said bars is 'passeda loop, I, made in the form of a letter E, the part 73 thereof having athreaded opening, '6, and entering the slots h in said bars. When thelatter are adjusted in length and the screws 41 tightened the loop I andstrips h h are firmly held together in their adjusted 7 5 positions.Such described construction of said loop is more plainly shown in Figs.8,9, and 10. The bars H are also provided with holes 78, as and forthepurpose hereinafter set forth.

If desired, the cross-bars G may be dispensed So with, and the bars H beprovided with loops 9 g for the ends Fto pass through. So, too, insteadof employing the screws f f a spring hook or pin, G, may be used, asplainly shown in Fig. 16. a

The springs G, which are located around the edges of the bed-bottom,have upper loops, 0 0 c and lower loops or eyes, 0 c" 0 which may beround or oblong to correspond to the outline of the frame or slatpassing therethrough, as plainly shown in Fig. 3. The sides and ends ofthe upper and lower frames pass respectivelythrough the loops 0 0 sothat said parts are thereby all relatively secured together.

The springs C have upwardly projecting pins 0 at their bottoms, (seeFigs. 6 and 7,) which are designed to enter the openings h in I loopedends 0 (J for the passage of the side bars of the frames B B. Thesesprings are located 'on the long sides of the bed-bottom, as shown inFig. 1, for the purpose of imparting additional strength and elasticityto the bed'hottom at said parts. The connection of said springs with thebed-bottom is more plainly indicated in Fig. 4. The springs O O arefurther connected to each other and to the frames by means of chains Itand snap or spring hooks 70. (See Fig. 1.) In lieu of-the chains,sliding rods k may be used, and rings or eyes k may be placed upon theframes B B wherever needed for the snap or spring hooks, as shown at m,Fig. 1. A chain-connection is also made between the cornersfand thesprings, as shown at z z, Fig. 1, and for this reason said corners areprovided with the openingsf, as above set forth. The snap or springhooks are designed to enter the loops 0' 0 c of springs O, and thesprings O are also provided with correspondingloops, 0 0 for likepurpose. If desired, however, the snaps may connect with the. coils ofthe springs. Such connections are fully shown in Fig. 1. The springs G 0may therefore be formed with two or more loops, as desired. So, too, thesprings 0 maybe arranged in respect to the framesB B as shown in Figs.15 and 17, in which case the frames are not only connected with thesprings, but they also rest directly thereon.

In Figs. 13 and 14, I have shown my im provements applied to awoven-wire, tick, or other bottom, said wire or tick being secured toframe B by means of the rings k chains 7:, and snap or spring hooks 7t.

A bed-bottom constructed as above de scribed can be altered to any givensize, so

' that it may be readily made to fit either a sin- For instance, theright and left screw connection in the ends of frames B may be dispensedwith, andin lieu thereof notches may be formed on the rods b, and thesleeves E provided with an opening through which passes a spring or snapcatch to engage with one of said notches, substantially as shown for thebars or strips f in Fig. 16. So, too, the ends of said frames B B may bedispensed with, in which case only their sides will be used, and thebed-bob tom will still have an adjustment both in length and width.

If desired, the loops 0 on the springs C may be formed in the shape of aspring or snap hook, as shown in Fig. 5.

2. A bed-bottom composed of side and end bars capable of being extendedor contracted, in combination with means for retaining said parts intheir adjusted positions, substantially as shown and described.

3. A bed-bottom composed of an upper and a lower frame capable oflongitudinal and lateral adjustment, springs attached thereto, and aslat bottom, substantially as shown and described.

4. The combination, in a bed-bottom, of upper and lower frames which arecapable of longitudinal and lateral adj ustment. means for holding saidframes in their adjusted positions, and springs secured to said framesand to bottom slats composed ofslidingor adj ustable sections,substantially as shown and described.

7. In combination with the frames B B, the

springs O 0, having two or more loops, 0 c and chains 70, with snap orspring books It, substantially as shown and described.

'S. In combination with a frame capable of lateral and longitudinaladjustment, a spring or flexible bottom connected to said frame by meansofchains and spring or snap hooks, substantially as shown and described.

9. In combination with the frames B B, the springs O 0 O adjustableslats H H, and cross bars G, substantially as shown and described.

10., The combination of frames 13 13, having longitudinal and lateraladjustment, springs (1 0, having two or more loops, 0 0, bars H H, andchains k, with snap or spring hooks k,'substantially as shown anddescribed.

11. A bed-spring having one or more loops at its upper extremity and anupwardly projecting pin at its lower end, substantially as shown anddescribed.

12. A bed-bottom composed offrames having sectional sides and ends, andsprings secured thereto and to sectional bottom slats, substantially asshown and described.

18. In a bed-bottom, the combination offrame springs 0, having pin 0substantially as shown and described.

15. The frame B, having adjustable side and end bars, with corners j,having openings f, substantially as shown and described.
